Donning a princess-like tube dress, Collins is joined by Julia Roberts who keeps it simple in a formal blazer as she arrives at the screening event taking place at the Grauman's Chinese Theatre.

Lily Collins oozed her lovely princess persona while attending the Los Angeles premiere of her upcoming Snow White film, "Mirror Mirror". Stealing the limelight during the event taking place at the Grauman's Chinese Theatre, Collins became the belle of the ball as she stepped on the red carpet in her gorgeous ball gown.

The daughter of rock legend Phil Collins looked stunning in a Dolce&Gabbana puffy tube dress while posing with an artificial magic wand for the cameramen. Sporting daring red lipstick, the actress finished off her fabulous look with Giuseppe Zanotti heels, a Salvatore Ferragamo clutch, and H Stern jewels.

Collins was joined by her Oscar-winning co-star Julia Roberts, who kept it simple in a pink shirt that she paired with a black blazer and matching pants. Also spotted on the red carpet were a group of models who dressed in various colorful period dresses complete with extraordinary hairdos.

Leading man Armie Hammer, meanwhile, reportedly missed his flight and couldn't make it to the special screening. He, however, attended the after-party at the Roosevelt Hotel, where Collins was surprised with a giant apple shaped birthday cake to celebrate her twenty third birthday which took place on Sunday, March 18.

"Mirror Mirror" is a retelling of one of the most beloved fables of all time. The film will eschew the traditional story in favor of a more modern tale full of comedy and adventure. After her evil stepmother kills her father and destroys the kingdom, Snow White bands together with a gang of seven quarrelsome dwarves to reclaim what is rightly hers.

Directed by "Immortals" helmer Tarsem Singh, the adventure comedy movie is scheduled to open wide in the U.S. on March 30.
